LABEL-FEEDING MECHANISH.

Original application led Hay 12, 1922, Serial No. 560,365. Divided and this application illed November 10, 1 923. Serial No. 674,063.

To all wlwm it may conce/m:

Be it known that We, EDWARD HAAs and MILFORD B. FERGUSON, citizens of the United States, residing at Brooklyn, in the county of Kings, in the State of New York, have f invented certain new and useful Improvements in Label-Feeding Mechanisms, of which the followingis a specification.

The invention relates to an improvement in label feeding mechanisms. The present application is a division of our co ending application Serial N o. 560,365, filed ay 12, 1922.

The label feeding mechanism of the present invention is illustrated and described in said application as applied. to and forming part of the novel wrapping machine which is the subject matter of said application, and for convenience the improved label feeding mechanism is described and illustrated herein as applied to said wrapping machine. Only such parts of the wrapping machine are` shown in the drawings as are necessary to bring out the connection between the feeding mechanism and the wrapping machine. For a complete description of the relation between the mechanism and the machine, refe'ience may be had to said application. Although the improved label feeding mechanism is described and shown. as applied to a wrapping machine, it will be understood that the invention'is not to be restricted to this use inasmuch as it is adapted for application to and use in connection with various other kinds of machines.

The object of the invention is to produce an improved label feeding mechanism having provision for transferring a label from one point to another on the same plane. In the illustrated form of the invention the labels are supplied to the feeding mechanism on a horizontal plane and are transferred on that plane from the point at which the feeding mechanism receives the labels to the point at which they are delivered to the wrapping or' other machine to which the labels are to be delivered. The improved vlabel feeding mechanism is also adapted for transferring labels from one point to another on other than the horizontal plane. The labels are supplied to the mechanism for transfer to the machine for acting upon them one at a time and thisvmay be done by any preferred label supplying means. .The novel features of the invention include a `and is particularly platform, means for actuating the platform to transfer the label from the receiving point to the point of deliver means for properly positioning the label on the platform, means or clamping the label on the platform during the transferring movement and means for releasing the label when it has` been properly positioned to be acted upon by the machlne to which it is delivered. The inventlon is more fully described hereinafter pointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanying drawings, 1n which Fig. 1 is a vertical -section through the improved label feeding mechanism, together with an elevation of certain of the parts of the wrapping machine to which the label feeding mechanism is shown applied in said application; Fig. 2 is a plan of the label feeding mechanism (with certain of the actuating parts removed) 'showing the platform in position to receive a label; Fig. 3 is a. View similar to Fig. 2 with the platform turned at an angle of 90 to deliver the label to the machine to which the feeding mechanism is applied; F ig. 4 is a side elevation of certain of the actuating parts; Fig. 5 is a front elevation of the rolls, and associated parts, for supplying the labels one at a time to the feeding mechanism; and Fig. 6 is a transverse section across the label guide.

The improved label feeding mechanism comprises a platform 1 supported on a bracket 2 secured to the lower end of a vertically arranged shaft 3 journaled in a hub 4 integral with a bracket 5 which is supported from a part of the Wrapping machine to which the label feeding mechanism is supplied. ,The platform 1 is arc-shaped and is of such length that while one end is delivering a label in the desired position to the wrapping machine the other end may act as a guide for the next label to be supplied to the mechanism'. In the illustrated embodiment of the invention the labels are supplied to the mechanism at right angles to the. position at which they are delivered to the wrapping or other machine.

The platform 1 is shown in Fig. 2 in position to receive a label 6 from the label supplying means. Fig. 3 shows the position of the platform as it holds the label at the point of delivery to the wrapping machine. This movement through an angle of 90O is imparted to the shaft 3 and to the platform by means of a cam 7 mounted on a cam shaft 8 which is actuated from a source of power.

not shown. The connections between the cam 7 and the shaft 3 comprise anv arm 74 secured to the shaft 9 and carrying on its free end a roll 75 which travels in a. cam

l intermittently in timed relation with the movements of the machine to which the labels are delivered. y f.

When the platform has delivered a label 6 as is shown in Fig. 3 and has swung back to'the position shown in Fig. V2 to receive the next label, the turned-up edge 12 of an end extension 13 adjustably secured to the platform engages the label which has just been supplied to the mechanism and presses it against the inner side of an adjustable guide 14 secured to and extending toward the feeding mechanism from the frame 15 of the wrapping machine. By this means the label is properly positioned on the platform. Thereupon the clam arm 16 provided at its free end and with a felt gri ping means 17 is actuated to press and ho d the label firmly against the platform.

The clamp arm 16 is pivotallymounted at 18 on an ear 19 rising from the bracket 2. The clampV arm 16 is actuated to hold the label against the platform and to release the label by means of a cam 20 mounted on the camshaft 8. The connections between the cam 20 and the clamp 16 comprise a cam roll 21 carried by the upper'end of a rod 22 which is bifurcated and straddles the cam shaft 8. The lower end of the rod 22 (which is adjustable in length) is pivotally connected with a .horizontally disposed link 23 pivotally connected at its other end with a boss 24 depending from the bracket 5.? The link 23 is provided with a lug carryingl a pin 25 which is engaged in a groove formed in a collar 26 loosely mounted on the shaft 3. Also engaged in the grooved collar 26 is a pin 27 projecting laterally from the clamp arm 16. Thus the active part of the cam 2O serves to raise the clamp arm 16 and release the label. This occurs when platform l and the label 6 arefin the position shown in Fig. 3. The clamp is depressed to hold the label against the platform by force of gravity. `Thusthe roll 21 is held in contactpwith the cam 20 by the weight of the parts connected with it.

The means for supplying the labels one at a time to the improved label feeding mechanism comprises a. platform 28 upon which the labels are stacked, as shown inFig. 1. The platform 28 is mountedon' the upper end of a` vertically arranged rack 29 which The labels are stripped from the f 'ausgabe is yieldingly pressed upwardly. This construction, which is supported from the front of the wrapping machine bfy well-known and requires no urther descri tion. The labels` are pressed upwardly against the holding needle 30 supported on an arm 31 adjustably secured in a bracket ile and' delivered to the machine one at a time by a rubber, ratchet-controlled, wheel 33 when the pawl 34 is in engagement with the ratchet w eel 35. When the pawl 34 is out of engagement with the ratchet wheel, the rubber wheel 33 travels backl and forth on the pile of labels without deliverin them. The wheel 33 is carried by the o set end of a lever 36 pivotally mounted on the lower end of an arm 37 secured to the shaft 38 journaled in brackets 39. 'The vwheel 33 bis yieldingly held in engagement with the pile-of labels by a spring 40.' The arm 37 is oscillated to cause wheel 33 to travel backr rolls which deliver the label to the feeding a bracket, is.

mechanism. The upper set of rolls 45 (Fig. v

5) are mounted on the shaft 42 and travel in a clockwise direction, viewing Fig. 1.

The lower set of rolls 46 are secured to a shaft 47 journaled in the forward ends of arms 48 pivotally mounted on a bracket 49.

The rolls 46 are held in yielding engagement with the rolls 45 by means of the spring 50. The rolls 46 are driven in a counter-clockwise direction and for this purpose'the shaft 42 is provided with a gearv 51 which meshes with a gear 52 mounted on shaft 47. The left hand end of the shaft 42 carries a bevel gear 53 which meshes with a corresponding gear 54 fixed on a shaft 55 journaled in' the machine fra-me, and which carries a sprocket wheel 56 which is vdriven by a second sprocket wheel 57 mounted on the cam shaft 8. The sprocket wheels are connected by a chain 58.- Pro er tension is imparted to the chain by an i ler sprocket 59 mounted yon the stud 60.

The feed rolls 45 and 46 deliver the label in position to be clamped against the platform 1. The labels vary in length and some labels are of such length that it is not eX- pedient that they pass entirely through the feed roll before they are gripped and swung into the desired position. When this is the case, and in order that the labels may move freely from between the feed rolls,.theJ shaft 42 is provided with a cam 61 (Fig. 5). the active part of which is adapted to contact with a roll 62 mounted on the shaft 47 and thereby swing the shaft 47 downwardl and the rolls 46 out of contact with the label and the rolls 45.` When the active part of the cam 61 has passed out of engagement with the roll 62, the spring 50 returns gear 52 and rolls 46 to normal position in engagement with gear 51 and rolls 46. l p

As the label is swung from the point where it is supplied tothe mechanism to the point where it is to be delivered to the wrapping or other machine, `it passes between'upper and lower guide rods 63 and 64 (Fig. 1). The feed rolls 45 and 46 supply the labels to the feeding mechanism bet-ween an upper guide 65 having an upturned forward end 66 and a lower guide 67. The swing of the platform into position to receive the label and into the desired position to deliver the label is determined respectively by the stop rods 68 and 69.
